I am loosing that ability to do "energy boosts" and I am loosing it fast. I used to train in a way when I mixed slower routines with a series of fast explosive movements (it was not related to endurance training but rather a mix between free-running and martial arts). So, shortly, I just cant do that anymore - its not like I dont have stamina or run out of breath, I just dont have energy to put into my movements. On the other hand, my endurance has sky-rocketed - I now complete my one hour running route without any stops, when previously in average I needed 2-3 stops. Though, I am definitely running slower.
I am curious to challenge one of my friends for a couple of arm-wrestling rounds - just to make sure. Something inside of me keeps telling that I am up for some "surprises" there too... And, btw, arm-wrestling requires a bit of that "boosting" and putting a lot of energy into short-timed efforts too.
